Vbulletin forum and affiliation

[libbert]

Hi all

Is it possible to make a link to my forum registration formula so that the registration form contains a certain user name in the " Referrer:" field?

For example I want it to say "Libbert" in the registration field to my forum when clicking on a link. Is that possible?

The situation is that I will be running an affiliation program to my forum. So to make it easy for other webmaster if would help if the webmaster automatically gets his user name in the "Referrer" field.

Hope this made sense,

Thanks
